Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

The moment of inertia of the wheel is 0.593 kg-m².

Explanation:

Given that,

Force = 82.0 N

Radius r = 0.150 m

Angular speed = 12.8 rev/s

Time = 3.88 s

We need to calculate the torque

Using formula of torque

Now, The angular acceleration

We need to calculate the moment of inertia

Using relation between torque and moment of inertia

Hence, The moment of inertia of the wheel is 0.593 kg-m².

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
